SourceList - Manage a list of sources
The Source List class provides access to a list of sources. It
can read them from a file and generate a list of all the distinct
sources.
All sources have a type associated with them that defines the layout
of the archive. The exact format of the file is documented in
files.sgml.
The types are mapped through a list of type definitions which handle
the actual construction of the back end type. After loading a source
list all you have is a list of package index files that have the ability
to be Acquired.
The vendor machanism is similar, except the vendor types are hard
wired. Before loading the source list the vendor list is loaded.
This doesn't load key data, just the checks to perform.
